<p>Fossil is a simple, high-reliability, distributed software configuration

On Unix systems, the configuration database is named ".fossil" and is
located in the user's home directory.  On Windows, the configuration
database is named "_fossil" (using an underscore as the first character
instead of a dot) and is located in the directory specified by the
LOCALAPPDATA, APPDATA, or HOMEPATH environment variables, in that order.

You can override this default location by defining the environment
variable FOSSIL_HOME pointing to an appropriate (writable) directory.

<h3>2.2 Repository Databases</h3>

The repository database is the file that is commonly referred to as

name of the project, with a ".fossil" suffix.  For example, the repository
